摘　　要：为了减少传递到水下航行器探测声学阵列承压板的振动能量,基于声学黑洞原理设计了一种减振圆板附属结构。采用加速度振级落差表征其减振性能,并分别开展了激振器轴向和径向激励下的承压板减振性能试验。研究结果表明,该减振圆板结构在50 Hz~10 kHz的频率范围内减振效果良好,充分说明了文中设计的减振圆板附属结构具有轻质、高效、宽频的减振特点,拥有广泛的潜在应用价值。In order to reduce the vibration energy transferred to the bearing plate of an undersea vehicle for detecting acoustic arrays,an accessory round plate structure for vibration reduction was designed based on the acoustic black hole principle.The vibration reduction performance was characterized by the vibration level drop of acceleration,and the vibration reduction performance tests of the bearing plate under axial and radial excitation of the shaker were carried out.The results show that the vibration reduction effect of the round plate structure is good in the frequency range of 50 Hz–10 kHz,fully showing that the accessory round plate structure designed in this paper has the vibration reduction characteristics of light weight,high efficiency,and wide frequency and has a wide range of potential application value.
